Invopop is an officially certified invoice provider in Portugal. Our AT Portugal app supports invoice, receipt and delivery note compliance with Portugal’s AT e-invoicing regulation. Automate supplier onboarding, SAF-T report generation, invoice generation with ATCUD, and more. This app enables businesses (and their suppliers) to issue invoices and other document types in accordance with Portuguese law.Key Features

Workflow automation: This app provides automated workflows for issuing invoices, onboarding suppliers, and managing fiscal submissions to the Autoridade Tributária e Aduaneira (AT).
Legally compliant PDF documents: Invoices, payments and delivery notes are generated with a certified ATCUD and QR codes, as required by the Portuguese tax legislation.
SAF-T (PT): The app makes workflow steps available to manage SAF-T (PT) entries for each supplier.
Realtime and manual reporting options: Report in real-time via webservice or generate a file to upload through the AT’s portal.
Supplier portal: Suppliers can generate SAF-T PT reports and create authorized series via the Supplier Portal.
Supplier registration: Automatic registration (no onboarding process) with a single workflow step.
White-label support: Invoicing can be performed either under a client’s brand (white-label) or directly by the issuing organization, according to operational needs.

FAQ

Invoicing questions

Should our customers upload their SAF-T files manually?

In Portugal, fiscally relevant documents issued through invoicing software must be reported to the Tax Authority (AT). There are two possible reporting models:

SAF-T monthly export – a single XML file including all documents for the month. This file is generated by the invoicing software and then uploaded manually to the AT portal, as there is no API available for submitting it automatically.
Real-time transmission – instead of a monthly file, each invoice is sent individually to the AT at the time of issuance, using the authority’s API.

Whether one model or the other is used usually depends on the issuer’s accountant’s preference (who typically uploads the SAF-T monthly report should they choose that model). Invopop’s AT Portugal app supports both reporting methods, so each supplier can pick the one that best fits their needs.

How do I configure my workspace for Portuguese invoicing?

Install the AT Portugal app, register the supplier with their NIF, and pick a reporting model (monthly SAF-T or real-time submission). Run invoices through the AT Issue Invoice workflow — Invopop generates the ATCUD, QR, and signature automatically.

Why does recording fail with 'payable: too high according to Artigo 40.º do CIVA'?

When issuing in Portugal you may see an error similar to:

recording envelope: totals: (payable: too high according to Artigo 40.º do CIVA.)

What it means: Article 40 of the Portuguese VAT Code (Código do IVA) sets limits and rules for simplified invoices (faturas simplificadas). If the payable amount exceeds what is allowed for a simplified invoice in your situation, the rules effectively require a full invoice (fatura completa) with proper buyer identification—not an anonymous or minimal customer.What to do:

Treat the document as a full invoice and supply real customer tax data when you have it.
If you do not have the buyer’s tax information, Portuguese practice allows the generic retail customer: set the customer name to Consumidor final and the tax ID to 999999990.
For transactions above €1,000, the law also expects name and address on the document. The AT may not always reject submissions that omit some of that detail, but you should follow the rule for full compliance.

Adjust your GOBL customer block (or equivalent) accordingly and re-run the workflow.

Why does my payment workflow fail with 'payment type RG is not supported for real-time reporting'?

This error means your workflow includes the Send to the AT step for a payment receipt. Payment receipts are not supported for real-time reporting — the AT does not accept them via the real-time webservice.The fix: remove the Send to the AT step from your payment workflow. RG receipts are only reportable through the monthly SAF-T file — the AT does not accept them via the real-time webservice. The Record for SAF-T reporting step alone is all you need for full compliance.

What payment receipt types are supported in Portugal?

Portugal defines two payment receipt types:

RG — Outros Recibos: Standard payment receipts, reported through the monthly SAF-T file only. Real-time reporting is not available for this type.
RC — Recibo no âmbito do regime de IVA de Caixa: Receipts specific to the VAT Cash accounting regime. RC payments are not currently supported by the AT Portugal app.

Where do I find Portugal-specific GOBL documentation?

See the Portugal tax regime in GOBL for tax categories, NIF rules, and AT-specific extensions. The pt-saft-v1 addon documents fields required by the SAF-T schema.

Registering supplier questions

How do I register a supplier with AT?

Run the AT Register Supplier workflow with the supplier’s NIF and chosen reporting model. Invopop registers the issuance series with AT and generates the ATCUD prefix to be embedded in every issued document.

What credentials does AT require to authenticate a supplier?

For real-time submission, an AT API username/password is required (issued through the AT portal). For SAF-T monthly export, no live credentials are needed — only the supplier’s NIF and series registration.

How are supplier credentials stored in Invopop for Portugal?

For real-time submission, Invopop stores AT API credentials encrypted at rest. For SAF-T export model, no live credentials are needed — the supplier (or their accountant) downloads the SAF-T file and uploads it manually to AT’s portal.

Reporting questions

How often must I submit AT reports?

Real-time model: per invoice. SAF-T model: once per month, by the 5th of the following month. The choice is set at supplier registration and can be changed by re-registering.

How do I schedule periodic reports for Portugal?

For invoice-level reporting, choose the model at supplier registration: real-time (Invopop submits per invoice) or monthly SAF-T (Invopop generates the file by the 5th of the following month, accountant uploads). Periodic VAT and IES are filed separately by the accountant.

What format does AT expect for periodic reports?

Monthly SAF-T-PT XML uploaded to AT’s portal (no API for this), or real-time WebService XML calls per invoice. Both follow the same SAF-T schema; real-time submits one document at a time, SAF-T submits an aggregated file covering the month.

AT B2B invoice

In this example, we’re issuing a simple invoice from a Portuguese supplier to another Portuguese business.Notice:

the minimal version in the first tab contains only the essential fields required to create the invoice, without totals or calculations,
the pt-saft-v1 addon ensures the document will be validated and normalized using the SAF-T PT v1 rules built into the GOBL library,
the supplier and series fields are set to example values; you’ll need to replace them with the details of supplier and series registered as per the previous sections. The series must be registered in the Supplier Portal and follow Portuguese naming conventions (see Series Management for details),
when running gobl build, or uploading the file, the system automatically calculates totals, assigns the pt-saft-invoice-type extension to FT (Fatura), sets the pt-saft-payment-means extension to CC for card payment, and applies the pt-saft-tax-rate extension to NOR for standard VAT,
the built version in the second tab shows the normalized document with calculated totals, line item sums (including advance payment deductions), tax breakdowns, and automatically generated fields, and,
the h item unit causes the pt-saft-product-type extension to be set to S (Serviço), and the pt-region extension is automatically set to PT.

AT delivery note

In this example, we’re issuing a delivery note from a Portuguese supplier to another Portuguese receiver.Notice:

the first tab shows the minimal version containing only the essential fields required to create the delivery document; there are no totals or calculations,
the pt-saft-v1 addon ensures the document will be validated and normalized using the SAF-T PT v1 rules built into the GOBL library,
the supplier and series fields are set to example values; you’ll need to replace them with the details of supplier and series registered as per the previous sections. The series must be registered in the Supplier Portal and follow Portuguese naming conventions (see Series Management for details),
this is an note document type with the pt-saft-movement-type extension set to GR (Guia de Remessa),
when running gobl build, or uploading the document, the system automatically calculates totals, applies the standard VAT rate with the pt-saft-tax-rate extension set to NOR, and normalizes all fields,
the second tab shows the built version of the document with the calculated totals, line item sums, tax breakdowns, and automatically generated fields, and,delivery
the pt-region extension is automatically set to PT.

AT return guide

A return guide (Guia de Devolução) records goods being returned to the supplier — for example, defective items, unsold stock, or any other scenario where previously delivered goods are sent back.Notice:

the document carries the return tag ($tags: ["return"]), which the pt-saft-v1 addon uses to automatically set the pt-saft-movement-type extension to GD (Guia de Devolução),
the series follows the GD prefix convention and must be registered through the Supplier Portal, and,
the flow of goods is reversed compared to a delivery note: the customer is the party returning the goods, and the supplier is the one receiving them back.

AT global waybill

For shipments where the specific recipient is not known upfront — for example, multi-stop delivery runs — issuers can emit a global waybill (Guia de Transporte Global) to cover the goods in transport.Notice:

the document type is set to waybill, which the pt-saft-v1 addon normalizes to the pt-saft-movement-type extension GT (Guia de Transporte),
the series follows the GT prefix convention required by the AT and must be registered through the Supplier Portal, and,
the customer field is omitted: when no customer is provided on a GT, the SAF-T submission auto-fills the AT-prescribed generic entry Consumidor final with NIF 999999990 and address Desconhecido.

AT delivery from global waybill

Once the recipient of part of the goods covered by a global waybill is known, a concrete document — typically a GR (Guia de Remessa) — must be issued with the full transaction details, including the customer and a cross-reference back to the originating GT so the AT can correlate both records.Notice:

the customer is now populated with the actual recipient of the goods, and,
the preceding array carries one entry with the series, code, and issue_date of the originating GT.

AT return from global waybill

A return can also be linked back to a global waybill — for example, when surplus goods that were not delivered to any customer come back to the depot at the end of a delivery run.Notice:

as in the standalone return guide, the return tag drives the pt-saft-movement-type extension to GD,
the preceding array references the originating GT, and,
the customer is omitted, since the goods are returning to the issuer’s own depot rather than to a specific party.

AT payment receipt

In this example, we’re issuing a payment receipt from a Portuguese supplier to another Portuguese business.Notice:

the minimal version (payment.min.mdx) contains only the essential fields required to create the payment document,
the pt-saft-v1 addon ensures the document will be validated and normalized using the SAF-T PT v1 rules built into the GOBL library,
the supplier and series fields are set to example values; you’ll need to replace them with the details of supplier and series registered as per the previous sections. The series must be registered in the Supplier Portal and follow Portuguese naming conventions (see Series Management for details),
this is a single receipt payment that bundles multiple payment methods: 30,00 EUR in cash plus 31,50 EUR by card, summing to the document total of 61,50 EUR. Each method gets its own pt-saft-payment-means extension auto-assigned (NU for cash, CC for card),
when running gobl build, the system automatically assigns the pt-saft-payment-type extension to RG and the pt-saft-source extension to P,
the built version (payment.mdx) shows the normalized document with all automatically generated fields and extensions properly set,
the payment lines reference the original invoice being paid, though a single receipt can reference multiple invoices if needed,
this receipt could represent either a full or partial payment of the referenced invoice; it simply records the amounts and taxes being paid, so the total may or may not cover the full invoice amount, and,
there are no calculations in the minimal version; all normalizations will be made automatically when uploading.
